A little scared…

Hi everyone, so I just found out I was pregnant on 9/21/22 (two days after a missed period). Around the time of my ovulation, I randomly took a Bactrim because I felt the signs and symptoms of a UTI coming on. I had these laying around because I had a UTI about 8 months ago and I didn’t finish the prescription, so I had them still. Should I be worried?

My last menstrual cycle started:

august 22,2022

I don’t know the exact days, but I know for sure I randomly took a Bactrim closer to the beginning of September, possibly the second week. I wasn’t taking them on a regular basis, just took a pill or two for two days.
